April 14 meeting: intro to iSCSI and cost effective NAS

Topic: A practical introduction to iSCSI and cost effective NAS solutions
Presenter: Jon Magrini
When: 7PM, Thursday April 14, 2011
Where: Red Hat Worldwide Headquarters
Permalink: http://trilug.org/2011-04-14/storage

Bio: Jon Magrini is a Red Hat TSE in the Storage SBR at Red Hat and joined their team a little over a year ago. His specialty is clustering, with a focus on storage related technologies. Jon's Linux experience started in the early 2000 era when he worked for Borland software and developed pluggable modules, using a pure java open-api for software products such as JBuilder and Together Control Center. His interest for storage started with employment at Red Hat and the purchase of his own EMC CLARiiON, which started a waterfall effect.

March 10 meeting - High Availability, Low Dollar Load Balancing

Synposis: True high availability load balancing traditionally involves specialized, expensive hardware and software. However, you can build advanced, high availability configurations without a single point of failure using nothing but open source tools and commodity hardware. This talk will include a discussion of several tools, configurations, and advantages and disadvantages thereof. All tools involved are 100% free and open source. As a bonus topic, Simon will tell you how to use open source load balancing tools to IPv6-enable your IPv4-only infrastructure with minimal risk, time and hassle.

About the Speaker: Simon Karpen is the system architect / wearer of many hats for VoiceThread, which provides a very powerful rich media asynchronous collaboration platform. He has also worked for the Shodor Education Foundation in the past, and is a current NCSU MBA student (class of May, 2011). Simon is a member of the NC*SA Steering Committee.

February 10 meeting - Hacking with Backtrack and Metasploit

When we deploy Linux servers on the Internet, they are exposed to the entire world, and they may be vulnerable to attacks. How can we know that they are secure?

As part of the security team at SAS, Ryan Linn tests systems against vulnerabilities, and he recommends ways to mitigate the risks. The tools that he uses are open source, and very sophisticated.

Ryan will introduce us to Backtrack4, the LiveCD with hacking in mind. He will show us how to use the tools to scan a network for vulnerable machines, test a target machine against a list of known vulnerabilities, and how to take control over a machine. PWN3D.

The world-wide Internet - you will never find a more wretched hive of scum and villainy. Backtrack4 is a must-have tool for anyone planning to put a computer into that environment.

New SSL certificates for web & mail

It's that time of year again. We have regenerated our SSL certificates for our web and mail servers. Most people will notice this when their email client tries to connect to "mail.trilug.org" (which is the server name that you should use). It will warn that the certificate has changed. The new mail certificate fingerprints are:

SHA1 = 92:8A:60:97:6C:A9:37:C7:67:E4:A7:65:92:2E:06:65:64:CD:A0:5F
MD5 = DF:00:29:BB:0D:99:6F:BA:58:06:0A:86:9E:DD:9D:CB

LUG Organizational Choices, Summary, 13 January 2011

Ten years ago, TriLUG started operating as a North Carolina non-profit
corporation, in order to accept hardware and monetary donations, in turn
re-donating to schools and local LUGs, acting as an incubator for promoting
Linux. Over time, Linux has become more mainstream, is accepted in the
business world, and even used at schools. TriLUG's mission has therefore
changed accordingly, to become more of an educational and social group for
technology and Open Source. Although we're still devoted to education and
outreach, our income and expenses are now related to pizza and meetings.

We are run by a Steering Committee whose membership changes by vote every
year in May. This committee is a group of volunteers, which mean the
committee members have a significantly limited amount of time and energy to
invest in running TriLUG. These two facts have led to a problem that TriLUG
now faces: Over time, the Steering Committee has focused it's efforts on
finding meeting speakers, donors, sponsors, and pizza; and maintaining our
online resources. The annual Steering Committee hand-offs and corporate
bureaucratic tasks have taken a back seat, to the point that we have been
delinquent in corporate paperwork and tax filings. In fact, we are just a
hair's breadth from losing our NC non-profit status and our Federal EIN.

TriLUG is now faced with a decision, upon which we must vote. We must
choose between one of two options.

Do we want to keep the non-profit corporate status which we've not really
used nor needed as of late? If we choose this option, it means that we MUST
spend the time and energy (and possibly even money) required to dig
ourselves out of a deep paperwork hole in order to prove to the IRS and the
State of North Carolina that we desire and deserve to keep the status. In
order for this option to function, we must have volunteers (other than the
current Steering Committee) who will stand up to do the necessary backlog
work. In addition, future Steering Committees MUST be responsible for the
bureaucratic tasks necessary for maintaining the non-profit corporate
status.

On the other hand, do we opt to dissolve TriLUG as a corporation, and become
an informal user group, handling money for pizza and speakers by using a DBA
bank account? This choice allows our current and future Steering Committees
to focus on providing speakers and pizza for meetings, and maintaining our
online resources, and frees us from worrying about meeting (or failing to
meet) corporate status requirements and performing the bureaucratic tasks
necessary to maintain a non-profit corporation.

As you consider the two choices, keep in mind that TriLUG has no current
need for non-profit corporate status, and that if we dissolve the
corporation now, at any time in the future we decide we need it, we can do what is
necessary then to re-incorporate. Also, consider that that at the
organizational meeting held in December to to discuss these matters, the
opinion of the majority of those attending was that we no longer need to be
a non-profit corporation. Finally, if we choose to keep our current
corporate status, it is imperative that those who choose this MUST stand up
and invest themselves in making it happen, or the choice WILL fail!

Members of TriLUG, for which option will you vote?

If you would like to listen to the recording of the Organizational Meeting that was held on December 2nd, 2010, wherein our current status and viable options for action were discussed (keep in mind it was a long meeting, at 2 hours and 50 minutes), you can access the recording at:
